1) Many species of lizards can break off their tail when attacked by predators. A herpetologist hypothesizes that lizards that have lost their tail can sprint faster than those that have a tail. To test this idea the herpetologist collects 8 adult Tokay geckos and records their maximum sprinting speed (centimeters per second) before and after surgically removing the tail. The results of such experiment are reported on the following table: Subject 1 2 3 4 5 6 7 8 Average SD Before removing the tail 9.3 7.8 8.3 9.6 7.7 8.8 8.2 9.0 8.6 0.70 After removing the tail 10.2 7.7 9.2 9.4 8.5 9.5 8.7 9.4 9.1 0.76 Difference -0.9 0.1 -0.9 0.2 -0.8 -0.7 -0.5 -0.4 -0.49 0.43 Using this dataset conduct a hypothesis test for the herpetologist's prediction.
